Realistically speaking, nobody wants to work on a very old codebase. That said, should you want to contribute some bug fixes, or some improvements here and there, help is welcome.
Keep in mind I started the website all the way back in the August 2005. The website was pretty much one-php-script-per-page for the first year. It was known then as "Reviewing the Kanji". A year or so later, I created a very barebones MVC inspired by Symfony 1. Thankfully because I followed the same API and conventions than Symfony a few years later I was able to refactor to the actual Symfony 1 package.
